This disclosure relates to an electrostatographic photosens-
itive device bearing a relatively thick (greater than 10
microns) layer of an insulating organic resin on its surface,
Various methods of forming ~ latent image on such a device are
described by Peter Mark in ____________________________

~ Vol. 18, No, 3, May/June 1974 (pp 254 261)

The disclosed concept involves the use of an ultraviolet or
far~blue sensitive photoconductor as an overcoating for the
underlying visible light sensitive photoconductor. The UV or
far-blue light induced conductivity of this photoconductive
overcoating provides an alternative means for achieving a
field distribution across the insulating overcoating and the
layer of photoconductive material,

By the use of such a photoconductive overcoating whose optical
sensitivity is complementary to that of the underlying photo-
conductor, it is possible to reduce the number of steps neces-
sary to form a latent image.
